Abstract

Eine Vorrichtung zur Magnetbürstenentwicklung elektrostatischer latenter Ladungsbilder auf Einzelblattaufzeichnungsträgern (11) enthält innerhalb eines rotierenden, die Magnetbürste tragenden Zylinders (28) eine Magnetanordnung (31), die während der Zeit, in der der Aufzeichnungsträger (11) mit seiner Vorderkante in den Entwicklungsbereich (B) bewegt wird, in eine Stellung gebracht werden kann, in der sie im Entwicklungsbereich (B) keine Magnetbürste erzeugt. Auf diese Weise wird verhindert, daß die Rückseite des Aufzeichnungsträgers (11) beim Eintreten der Vorderkante in den Entwicklungsbereich (B) durch Entwicklermaterial verunreinigt wird. Die Verstellung wird wieder rückgäng gemacht, sobald der Aufzeichnungsträger (11) eine Lage erreicht hat, in der Entwicklermaterial nicht mehr auf seine Rückseite gelangen kann.
